In mathematics, particularly, in analysis, Carleman's condition gives a sufficient condition for the determinacy of the moment problem. That is, if a measure satisfies Carleman's condition, there is no other measure having the same moments as The condition was discovered by Torsten Carleman in 1922.
Hamburger moment problem
For the Hamburger moment problem (the moment problem on the whole real line), the theorem states the following:
Let be a measure on such that all the moments

For the Stieltjes moment problem, the sufficient condition for determinacy is
